VDI 2164:2016-12

This standard defines the fundamentals for the use of latent-heat storage systems in building services. Recent developments in the field of phase-change-materials (PCMs) open the way to new systems and components allowing energy savings and increases in energy efficiency. As the use of regenerative energies expands, demand and generation no longer coincide, requiring the temporary storage of energy in the building. Based on the fundamentals specified in this standard, PCM systems are described, their planning and calculation explained, and performance parameters are identified. The standard comprehensively covers: passive surface heating and cooling systems (such as building materials, components), active surface heating and cooling systems (such as chilled ceilings), local ventilating systems for cooling purposes, centralised ventilating systems for heating and cooling, energy storage systems.
